The invention relates to an indirect refrigeration and air-conditioning unit and a control method thereof. The indirect refrigeration and air-conditioning unit includes a shell and heat exchange parts, an air inlet area is formed in the shell, and an air supply port and an air inlet communicating with the air intake area are opened on the shell. and the return port; the heat exchange element has a first heat exchange flow channel communicated with the air inlet area and a second heat exchange flow channel communicated with the first heat exchange flow channel, and the first heat exchange flow channel communicates with the air supply port to form a supply air flow The air supply channel is transported from the air inlet area to the room, and the second heat exchange flow channel communicates with the return flow port to form a return flow channel for the air flow back to the air intake area. The invention relates to an indirect refrigeration air-conditioning unit and a control method thereof, which can reduce the waste of cooling capacity.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to an indirect refrigeration air-conditioning unit and a control method thereof. Background technique [0002] With the development of refrigeration technology and the improvement of environmental awareness, the use of indirect refrigeration air-conditioning units is becoming more and more common. The indirect cooling air-conditioning unit uses the temperature difference between dry and wet bulbs as the driving force to cool air or water through water evaporation. In the traditional indirect refrigeration air-conditioning unit, the wet and cold air generated during the working process is directly discharged to the outside, resulting in a serious waste of cooling capacity. Contents of the invention [0003] Based on this, it is necessary to provide an indirect refrigeration air-conditioning unit capable of reducing the waste of cooling capacity and a control method thereof f...
